Four varieties of bacteria have been found in the bee bread of the larva: Bacillus circulans, B. coagulans, B. firmus, and B. megaterium. Only the Bacillus genus has been found in the samples taken. Together, these four species were able to hydrolyze starch, ferment glucose, convert nitrates to nitrites, and produce dihydroxyacetone from glycerol. This group of bacteria also lowers the pH of the bee bread. These functions serve not only to protect the larva from other bacteria, but they also digest complex molecules which allow the larva to easily absorb nutrients without expending a lot of energy. The bacteria, in turn, receive a supply of food which results in a mutualistic relationship.[13]
Vous avez passé par plusieurs étapes durant la construction de votre nouvelle résidence, maintenant que vous avez vos clés, vous êtes chez-vous... mais l’aventure n’est pas encore terminée. Compte tenu du nombre de systèmes, de produits et de matériaux utilisés pendant la construction, il faut vous attendre à ce que certains d’entre eux nécessitent des ajustements ou de légères modifications.
Au cours de la première année, la vapeur d'eau qui s'échappe des matériaux de structure (bois) et du béton favorise cette condensation. Il faut donc ventiler la maison d'une façon plus importante et adéquate. L'apport d'air frais est le seul moyen d'abaisser le taux d'humidité ambiant. La ventilation peut s'effectuer de façon naturelle par l'ouverture des portes et fenêtres ou de façon mécanique par l'utilisation d'un ventilateur.
Larger females are able to better control the size of their offspring. As stated in the Life Cycle section, more bee bread leads to larger offspring. Larger females are able to gather more pollen and nectar in a shorter amount of time when compared to smaller females. This means that during rich conditions, the larger females can have larger offspring with greater fitness, or if conditions are poor, the females can simply choose to have smaller offspring. There is a lower limit to how small offspring can be, and thus, smaller females can’t make this reduction or increase in size in response to the environment. Smaller females are still able to exist since larger females can’t take advantage of having larger offspring when the density of nesting grounds is low.[12] To put it another way, larger male offspring are less effective in low density nesting grounds since they don’t have as many opportunities to use their size to fight off other males; thus, in low density nesting grounds, small and large males have similar fitness which means that the extra bee bread which the larger male received served no purpose. Smaller males actually do better in low density areas because they don’t have to fight with larger males as much, and by extension, expend less energy. This lack of a reason to produce larger offspring reduces the fitness of the larger females since they have to dig larger tunnels to fit in, but still produce the same size offspring as smaller females.[12]
